If population is growing rapidly in an area, why may the need for schools increase?

Correct answer: Number of children and families may increase

Direct answer: A, the number of children and families may increase. Schools provide education to children, so planning for schools depends partly on the number and age structure of the population. Rapid population growth can add more families and more school-age children over time, increasing the need for classrooms, teachers, books, and other facilities. A is correct because it gives the relevant demographic reason. B is wrong: river numbers or size do not explain demand for schools. C is unrelated to educational demand and is not a consequence of population growth. D is the opposite of the likely situation; rapid growth is not explained by a birth rate that is always zero. The word “may” matters because the exact need also depends on migration, age distribution, attendance, and existing school capacity. Memory cue: more school-age children usually means greater education planning.
